Life Sciences

Communicate scientific information that common ancestry and biological evolution are supported by multiple lines of empirical evidence.

This chapter consists of topics like Evidence of Common Ancestry and Diversity - Genetic information provides evidence of evolution. DNAsequences vary among species, but there are many overlaps;in fact, the ongoing branching that produces multiple lines ofdescent can be inferred by comparing the DNA sequences ofdifferent organisms. Such information is also derivable from thesimilarities and differences in amino acid sequences and fromanatomical and embryological evidence. etc.

This topic covers various concepts like Trilobite Fossils, , etc.

This chapter consists of topics like Natural Selection - Natural selection occurs only if there is both (1) variation in thegenetic information between organisms in a population and (2)variation in the expression of that genetic information—that is,trait variation—that leads to differences in performance amongindividuals.The traits that positively affect survival are more likely to be reproduced, and thus are more common in the population. etc.

Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.

This chapter consists of topics like Adaptation - Changes in the physical environment, whether naturallyoccurring or human induced, have thus contributed to theexpansion of some species, the emergence of new distinctspecies as populations diverge under different conditions, and the decline–and sometimes the extinction–of some species.Species become extinct because they can no longer survive and reproduce in their altered environment. If members cannot adjust to change that is too fast or drastic, the opportunity for the species’ evolution is lost. etc.

Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species.

This chapter consists of topics like Adaptation - Natural selection leads to adaptation, that is, to a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. That is, the differential survival and reproduction of organisms in a population that have an advantageous heritable trait leads to an increase in the proportion of individuals in future generations that have the trait and to a decrease in the proportion of individuals that do not. etc.

Construct an explanation based on evidence for how natural selection leads to adaptation of populations.

This chapter consists of topics like Natural Selection - Natural selection occurs only if there is both (1) variation in the genetic information between organisms in a population and (2) variation in the expression of that genetic information—that is, trait variation—that leads to differences in performance among individuals. etc.

Construct an explanation based on evidence that the process of evolution primarily results from four factors: (1) the potential for a species to increase in number, (2) the heritable genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for limited resources, and (4) the proliferation of those organisms that are better able to survive and reproduce in the environment.
